EuroLinux Linux distribution capabilities and limits
This document describes the technology capabilities and limits for EuroLinux 6, 7, 8 and 9. Some are theoretical, as they are connected with source code/projects used in the system. Minimal limits represent limits for the systems for which support is generally available by the EuroLinux company. Our dedicated solutions like:
- system rebuilds with Gaia build stack
- EuroLinux container images
- EuroLinux cloud images
- EuroLinux for edge computing
- EuroLinux ARM 64 for IoT
- containers running on the EuroLinux container platform or any other Kubernetes-based platform
might run and be supported on the less resources than described in this document.
The theoretical limit (connected with a version of the software used) is marked
as (LIMIT), when limit supported and tested by upstream is provided as
default for EuroLinux. TBA means - To Be Announced.
Minimum logical CPU
All systems, physical or virtual, require at minimum 1 logical (physical or virtual) CPU core.
Maximum logical CPU
| Architecture | EuroLinux 6 | EuroLinux 7 | EuroLinux 8 | EuroLinux 9 |
|---|---|---|---|---|
| x86_64 | 448 (4096) | 768 (5120) | 768 (8192) | 1792 (8192) |
| ARM64 | X | X | 256 | 512 (4096) |
Minimum memory
These requirements are only for systems supported as VMs or Physical hosts. In most cases, it's possible to run a system without complications on less memory. The minimum requirements have been provided below because it might not be possible to support systems with less memory.
